Abstract
The development process of human embryo until blastocyst is well understood during the past 30 years, however, embryogenesis from blastocyst to pre-gastrulation was still remained a “black box”. Limited by research materials and culture technologies, the “black box” is still unopened. We recently established an extended three-dimensional (3D) culture system of human blastocysts (Xiang et al., Nature 577(7791):537–542, 2020). The 3D embryo culture system could enable human blastocyst growing up to early primitive streak anlage stage in vitro. Here, we introduce the detail protocol and notes of culturing human 3D embryos.
